 wherein seat width narrowing elements are slidably mounted to a top of the seating surface of the seat booster at mounting points, said seat width narrowing elements adapted to adjust the width of the seating surface of the seat booster by sliding over the seating surface of the seat booster, and 
 wherein the seat width narrowing elements slide at the mounting points, wherein at least one of the seat width narrowing elements is displaceable over the top of the seating surface and in a direction substantially parallel to the seating surface of the seat booster. 
 
     
     
       2. The seat modification assembly according to  claim 1 , wherein the seat width narrowing elements are provided with armrests. 
     
     
       3. The seat modification assembly according to  claim 1 , wherein the seat booster is formed as a child seat. 
     
     
       4. The seat modification assembly according to  claim 1 , wherein the seat booster is formed as an additional seat bottom cushion adapted to ergonomically support a handicapped person. 
     
     
       5. The seat modification assembly according to  claim 1 , wherein a second of the at least one seat modification element of the seat modification assembly is formed as a back support. 
     
     
       6. The seat modification assembly according to  claim 5 , wherein the back support is formed as a lumbar support. 
     
     
       7. The seat modification assembly according to  claim 5 , wherein a further seat modification element of the seat modification assembly is formed as a headrest. 
     
     
       8. The seat modification assembly according to  claim 1 , wherein a third of the at least one seat modification element of the seat modification assembly is formed as a headrest. 
     
     
       9. The seat modification assembly according to  claim 8 , wherein the headrest is formed with a head support area, and the headrest is adapted such that the width of said head support area is adjustable. 
     
     
       10. The seat modification assembly according to  claim 8 , wherein the headrest is adapted to support a head of a child. 
     
     
       11. The seat modification assembly according to  claim 1 , wherein the seat modification element has sections with different degrees of hardness. 
     
     
       12. The seat modification assembly according to  claim 1 , wherein at least one of the at least one mounting arrangement of the seat modification assembly is a zipper. 
     
     
       13. The seat modification assembly according to  claim 1 , wherein at least one of the at least one mounting arrangement of the seat modification assembly is a hook and loop fastener. 
     
     
       14. The seat modification assembly according to  claim 1 , wherein the seat width narrowing elements are detachably mounted to the seat booster. 
     
     
       15. An aircraft passenger seat comprising:
 a seat modification assembly comprising: 
 at least one seat modification element adapted to change the ergonomic seating profile of a passenger seat provided with the seat modification assembly, a first seat modification element of the seat modification assembly being formed as a seat booster having a seating surface, 
 wherein the at least one seat modification element comprises at least one mounting arrangement adapted to detachably mount the seat modification element to a portion of the passenger seat, and 
 the at least one mounting arrangement comprises a mounting device adapted for cooperation with at least one mounting device of the seat modification assembly, 
 wherein the at least one mounting device of the aircraft passenger seat is adapted to cooperate with at least one mounting device of the seat modification assembly so as to detachably mount the at least one seat modification element in a desired position at the aircraft passenger seat, 
 wherein seat width narrowing elements are slidably mounted to a top of the seating surface of the seat booster at mounting points, said seat width narrowing elements are adapted to adjust the width of the seating surface of the seat booster by sliding over the seating surface of the seat booster, and 
 wherein the seat width narrowing elements slide at the mounting points, wherein at least one of the seat width narrowing elements is displaceable over the top of the seating surface and in a direction substantially parallel to the seating surface of the seat booster. 
 
     
     
       16. The aircraft passenger seat according to  claim 15 , wherein at least one of the at least one mounting arrangement of the seat modification assembly is a zipper.
